Perfboard provides an extensive readout of system performance data for Mac OS X. Areas monitored include CPU load metrics, memory statistics, network bandwidth, and disk I/O operations. Feel your system has bogged down? Run Perfboard and check at a glance for problems such as excessive virtual memory paging, high network activity, lack of free memory, runaway processes and more. Perfboard is made available at no cost and you download and use it at your own risk.
Version 2.1 adds the addition of a workaround for a problem in Jaguar that sometimes prevented Perfboard from starting up properly.
